The only problem about this is:

class Fruit
{
class Seed {
void SetFruit(Fruit fruit)
{
this.outer = fruit;


Setting to pseudo variable 'outer' should be rejected in
compilation.
Please report it to bugzilla.

}
}
}

class Apple: Fruit
{
void AppleOnlyMethod(){ ... }

class AppleSeed: Fruit.Seed {
void DoSomething()
{
AppleOnlyMethod();
}
}

auto GetNewSeed() { return new AppleSeed(); }
}

auto apple = new Apple();
auto seed = apple.GetNewSeed();
seed.SetFruit(new Fruit());
seed.DoSomething(); //what happens here?

I will not report this, beacuse it will break my custom new operator
(template) for inner classes ;-)

That's most unwise, because if it's not supposed to be like that it will
get fixed anyway, so you better start replacing your custom new
operator.

Replacing my custom new operator exactly by what? Overloading the build
in new is deprecated...


class C{
     class D{

     }
}
void main(){
     auto c = new C;
     auto buf = new void[__traits(classInstanceSize, C.D)];
     (cast(byte[])buf)[] = typeid(C.D).init[];
     auto d = cast(C.D)buf.ptr;
     static if(is(typeof(d.__ctor()))) d.__ctor();
     enum offset=d.outer.offsetof;
     static assert(offset%C.sizeof==0);
     (cast(C[])buf)[offset/C.sizeof]=c;
     assert(d.outer is c);
}

Yes of course I can assign the reference by computing the address and then using that to assign it. But the point here is, that this is currently the only bug that is hepling me in what I'm doing, and I rather want the 7 other bugs I reported so far to be fixed, rather then the one that helps me.

Don't you understand? It doesn't matter how much a bug helps you (or anything else for that matter) if it's a bug - it's gonna be fixed. If you decided to abuse a bug - it's your problem and your problem alone. The earlier you start getting rid of that design, the easier it will be when the bug gets inevitable fixed.
